| Abstract: |
We present sensitive Australia Telescope Compact Array (ATCA)
observations of SiO masers in the inner parsecs of the Galactic
center (GC). We detected five SiO J=2–1, v=1 (86 GHz) masers in the
innner 25″ (1 pc) of the GC. All the detected 86 GHz
SiO masers are previously known SiO J=1–0, v=1 (43 GHz) masers and
associated with late-type stars. Eighteen 43 GHz SiO masers were
detected within 50″ (2 pc) of Sagittarius A*. Among
them, seven are detected for the first time, which brings the total
number of 43 GHz SiO masers to 22 in this region. |
